I am facing a strange problem solution: Our JVM (1.6) freezes from time to time (probably because of blocking threads or garbage collection) when running an application server. If we run the pstack command, the problem resolves.
Can somebody explain how pstack can resolve this freeze? I want to understand how a command that "only" reads stack traces is able to unblock/unfreeze the JVM in order to understand more about the freezes.
